For the first time, scientists have taken near-daily measurements of the Sun’s global coronal magnetic field, a region of the Sun that has only been observed irregularly in the past. The resulting ...

The left side illustrates a schematic of electric field observation of the space charge layer at the grain boundary. An electron beam tilted at various angles (tilt-scan-averaged electron beam) scans ...

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...
